All-time favorites in general, or all-time favorites adapted from books, or all-time favorite type of movies...?

I'll go with the second category for now. Or rather, let an expert handle it.

[John Cusack's voice] "Top Five Movies Adapted from Books. Individual titles, rather than series... and in no particular order. Reviewing the film, not the book, since each is a different medium... and should stand on its own."

5) To Kill a Mockingbird. "Gregory Peck unmissable as Atticus Finch in the adaptation of Harper Lee's signature work and sole novel. Plus, it's got a bird in the title, and a guy named Finch played by a guy named Peck." "Peck your heart out, Twitter."

4) Less Than Zero. "Rob Downey in '87, a 23-year-old cokehead, showing his early depth by playing... a 23-year-old cokehead. Charlie Sheen mysteriously unavailable or passed over for the role. Seriously, though, it's like St. Elmo's Fire on ecstasy -- nothing more perfectly captures the signature '80s paradox of capitalist anarchy among its youngest revelers. Alternate title? Occupy Rehab."

3) 1984 and A Clockwork Orange. "Dystopian society before it became all the rage. Or reality? All those early Mac ads and Big Brother Google notwithstanding... Man, as if the '60s weren't a visual acid trip anyway, a little ultra-violent Kubrick is enough to get your head spinning. By the way, Malcolm McDowell, in his later years, just perfectly British and misanthropic enough to play O'Brien in a remake. Or Conan, if he could fake a good Ricky Gervais impression, what with the ultra-violent Beard-pocalypse and all."

2) "Any of the movies of those kids' books that adults aren't supposed to enjoy, because they're kids' books, but are really too vivid and realistic for kids. The Secret of NIMH is one -- sure, they're cute mice, but they're experimental animals at the National Institutes of Mental Health. They're secret weapons of the CIA! Weren't Pinky & The Brain part of this Manchurian Rodent program or something?"

1) High Fidelity. "For... obvious reasons." "Besides -- I've read books like Love in the Time of Cholera and The Unbearable Lightness of Being. But if they ever made a book out of Evil Dead II, but I said I hadn't seen the first Evil Dead yet, then either I was going to see Evil Dead... or I'd be a cinematic idiot and a literary one too... But that word, yet, that means I'm not only going to see the movie, but also read the book. So there's still hope... yet."

Pulp Fiction - I love when a movie's dialogue is just good for its own sake, instead of serving to relentlessly advance the plot. So many iconic scenes, the music...sure, it might be copied and pasted from a dozen different sources, but Pulp Fiction is undeniably a great movie.

Predator - the perfect action movie. This one's on AMC about every other week and if I catch it, I usually have to finish it. Really two movies in one - the first part is a military shoot'em up in the jungle, the second part is a survivalist horror flick. Arnold gets lambasted for being a crummy actor, but he certainly has physical presence and charisma. Run, get to the choppa!

Blue Velvet - David Lynch's shining moment. Weird, dark, and sexy. Dennis Hopper is a madman. I love movies that utilize music well - I'm thinking of the creepy guy singing in the brothel.

Office Space - sure, it's a quiet little cult movie, but has any other film explored the drudgery of office life quite as well? Certainly, it's a forerunner to tv shows like the Office and Parks and Recreations. And once again, the gangsta rap soundtrack is killer.

And Raiders of the lost Ark. And Legally Blond. And I'd never admit this to anyone except you guys, but I love Pretty Woman. Yes, it's totally sexist and ridiculous, but it's so fun.

Sorry for coming so late to the party on this one.... but Mira! After reading this, maybe I'll give Beauty and the Beast a go. Plus, Willy Wonka and the Devil Wears Prada are such classics.

I'd say the Lord of the Rings (all three of them.) And (drum roll for the embarrassing) Mamma Mia! The first Pirates of the Caribbean, Stars Wars (the fourth one.) Oh, and Pride and Prejudice, the six part hour long BBC version. (Technically not a movie but aww well.) I'm sure I can think of more, but my mind has drawn a blank.
